CARBURETER.

Specification of Letters Patent.

PatentedNov. 16, 1915.

Application filed May 5, 1913. Serial No. 765,421;

To all whom it may concern Be' it known that I, MADISON F. BATES, a citizen' of the United States, residing at Lansing, county of Ingham, State of Michigan, have invented a certain new and useful Improvement in Carbureters; and declare the following to be a full, clear, and exact description of the same, such as will'enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to carburetersand consists in the improvements hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1, is a side elevation of a carbureter embodying my invention. Fig. 2, is a horizontal .section on the line B.B Figs. 1 and 4. Fig.

3, is a section on the line DD Figs. 1, 2 and 4. Fig. 4, is a section on the line EE Fig. 2.

a a represents the casing as a whole.

6 is the passage leading to the engine.

0 c are the intake passages.

d is an intake passage for theauxiliary air S pp y- 6 and g are disks integral with or secured upon the valve stem f which latter may reciprocate in the casing a.

2, is a port, the opening through which may be regulated by the disk 9, and 3 is a second port, the openin through which may be re ulated by the disk 6. These ports are at a istance apart equal to that of the disks e and 9 so that the opening through the one is equal to the opening through the other.

It is a spring tending to press the stern f and disks 9 and e to the position at which they leave the ports 2 and 3 open.

s is a lever arm, by which the stem f and disks 6 and 9 may be manipulated to regulate the opening through the ports 2 and 3.

i is a check valve adapted to open inward and when upon its seat to close the port forming a communication between the passage d and the outside air.

j, is a stem rising from the valve 2', and la is a spring acting to yieldingly press the valve 71 toward its seat.

m is the intake passage through which the liquid fuel is supplied to. a reservoir 11..

. There is a fioat valve mechanism in the reservoir n by which the level of the liquid fuel in said reservoir may be controlled.

0 is a conduit leading from the reservoir n below the level of the liquid therein and extending in two branches which terminate in the .nozzles q and 9" each of which opens into a branch of the intake passage 0.

One branch of the intake passage 0 communicates with the outlet passage 6 through the port 2 and the other through the port 3.

t is an intake passage for water, the open-' ing through which is controlled by an inwardly opening check valve u.

The maximum flow of liquid through the passage 0 is controlled by the needle valve 2 and through the conduit 02 by a needle valve 4). The conduit w opens into the passage 03 through the opening 10.

The operation of the above described de vice is as follows: The passage Z) is connected with the engine and the charge is drawn therethrough from the carbureter, the main air supplied passing in through the passages 0 0 taking up the combustible vapor from the nozzles q and 1' and distributing and thoroughly ,mixing the vapor and air as it passes through the narrow and extended openings past the disks 6 and g. Hydrocarbon is supplied through the passage m and is delivered, as described, through the nozzles g and 1-. Water is supplied through the passage t and conduit w. When the draft of the engine has increased to a sulficient. extent the valve to is raised permitting Water to pass through the conduit m and the valve 2' is drawn from its seat permitting the entrance of an auxiliary supply of air which takes up the water in the form of vapor and carries it through the ports 2 and 3 and thoroughly mixes it with the rest of the charge.

What I claim is:

1.- A carbureter havingtwo intake passages and an outlet passage, :1. port between each of said intake passages and said outlet passage, a disk valve adapted to regulate the opening through each of said ports by a movement perpendicular to the plane of said ports, said disks being joined together and adapted to open or close said ports by a simultaneous movement in the same direction, means for supplying a liquid to be vaporized and mixed with the air to each of said intake passages.

2. A carbureter having two intake passages and an outlet passage, a port between each of said intake passages and said outlet passage, a disk valve adapted to regulate the opening through each of said ports by a
